[linux-cifs-client] CIFS Client and DFS

[Stefan Grunenberg]

Sorry, but I can't help with suggestions in this topic.
If there is something new or planed, it will be great to hear about it, 
because we have the chance here to change lots of windows-desktops to 
Linux and this obstacle is in the way...
Thank's for your good work!
